As per my post it is Proprietary licensed. It follows the idea that the Developer / Company creates software and maintains control over its code, and therefore, its features and use.

Update: From sites like Software Licensing: Proprietary and Free and Open-Source Licenses - Video & Lesson Transcript | Study.com one can learn that Proprietary software consists of software that is licensed by the copyright holder under very specific conditions. In general, you can use the software, but you are not allowed to modify the software or distribute it to others.

The original source code for the software is not available, which means you can’t see the actual code written by the programmers. Proprietary software is, therefore, also referred to as closed-source software. This is done on purpose to protect the intellectual property invested in software development. If the source code were released, even with copyright restrictions, competitors could benefit from using this code.

Many proprietary software applications are also commercial, meaning that you have to pay for a license. However, many other proprietary software applications are free. The fact that software is free does not mean it is not proprietary.

There are numerous examples of proprietary software. Both the Windows and Mac operating systems are proprietary, and so are many of the typical software applications used in organizations, such as Microsoft Office. Many specialized software applications, such as those used for database management and various types of enterprise information systems, are also proprietary. In many cases, software companies have invested many years of software development into a product. By making the software proprietary, they are protecting their investment and making it possible to commercialize their software. The revenue from software sales can then be used to continue developing the software.

Shareware is proprietary software that is made available to users at no cost under certain conditions. For example, shareware may have limited functionality relative to the commercial version of the same software, or the license for the software may expire after a certain trial period. The rationale behind shareware is to give potential users the chance to evaluate the software before investing in a license fee. Trial versions of commercial software fall under the shareware category.
